Goldstar Crystalcast Investment Casting Powder 22.5kg (Crystal Cast) - TC0453

Gold Star Crystalcast is a plaster-bonded investment powder specifically designed for casting glass. The refractory content and permeability of Crystalcast enables firing cycles to temperatures as high as 900°C for as long as 10 days depending on the mould size.

Crystalcast has been formulated with a high-technology particle size distribution ensuring that every detail of the mould is reproduced with an exceptional surface finish. Gold Star has optimised the strength of this investment powder so that it permits the casting of small or large sculptures.

You can invest with slightly warmer water, the warmer the slurry is when investing the quicker the set time will be. We advise only a few degrees warmer than what you regularly use, as it may set too quick.
